Title:Well-posedness and Robust Preconditioners for Discretized Fluid-Structure Interaction Systems
Seminar:CCMA PDEs and Numerical Methods Seminar Series
Speaker:Kai Yang, Penn State
In our work we develop a family of preconditioners for the linear algebraic systems arising from the arbitrary Lagrangian-Eulerian discretization of some fluid-structure interaction models. After the time discretization, we formulate the fluid-structure interaction equations as saddle point problems and prove the uniform well-posedness. Then we discretize the space dimension by finite element methods and prove their uniform well-posedness by two different approaches under appropriate assumptions. The uniform well-posedness makes it possible to design robust preconditioners for the discretized fluid-structure interaction systems.
